BBS phase 1 & phase 2 high quality E. coli bin assembled genomes

<p>1,402&nbsp;<em>Escherichia coli</em> bin assembled genomes derived from the metagenome data collected as part of the <a href="https://www.ucl.ac.uk/global-health/research/a-z/baby-biome-study">BabyBiome study (BBS)</a> phase 1 &amp; phase 2.</p> <p>The data in this upload was first published as part of "<em>Group 2 and 3 ABC-transporter dependant K-antigen loci contribute significantly to variation in the invasive potential of Escherichia coli"</em>&nbsp; (Gladstone et al. 2024, to be released).</p> <h2>Files</h2> <p>Assembly data:</p> <ul> <li>BBS_E_coli_BAGs.tar: Archive containing sequences of the 1,402 bin assembled genomes.</li> <li>BBS_E_coli_metadata.tsv: Table linking the sequence assemblies to the subject data.</li> </ul> <p>Capsule predictions:</p> <ul> <li>BBS_E_coli_Kaptive_output.csv: Capsule predictions for all sequence data.</li> <li>BBS_E_coli_deduplicated_sequences_IDs.txt: Filenames for assemblies that constitute the 873 deduplicated sequences analysed in Gladstone et al. 2024.</li> </ul> <p>Quality control data:</p> <ul> <li>BBS_E_coli_demix_check_scores.tsv: Output from demix_check for the sequence assemblies.</li> <li>BBS_E_coli_checkm_results.tsv: Output from checkm.</li> <li>BBS_E_coli_gunc_results.tsv: Output from gunc.</li> </ul> <h2>Methods</h2> <h3>Bin assembled genomes</h3> <p>Source data:</p> <ul> <li>BBS phase 1: <a href="https://doi.org/10.1038/s41586-019-1560-1">Shao et al. 2019</a></li> <li>BBS phase 2: <a href="https://doi.org/10.1038/s41564-024-01804-9">Shao et al. 2024</a></li> </ul> <p>The data was produced using the mSWEEP and mGEMS pipeline (<a href="https://doi.org/10.12688/wellcomeopenres.15639.2">M&auml;klin et al. 2020</a> &amp; <a href="https://doi.org/10.1099/mgen.0.000691">M&auml;klin et al. 2021</a>) following the steps described in <a href="https://doi.org/10.1038/s41467-024-49591-5">Khawaja, M&auml;klin, Kallonen, et al. 2024</a>.</p> <h3>Quality control</h3> <p>The BAGs in this upload were filtered with demix_check (<a href="https://github.com/harry-thorpe/demix_check">https://github.com/harry-thorpe/demix_check</a>) and only those with a quality score 1 or 2 are included. For the capsule type annotations, contigs shorter than 5,000bp were removed but the short contigs are still present in the uploaded files). Further QC data is available from checkm (<a href="https://genome.cshlp.org/content/25/7/1043.short">Parks et al. 2015</a>) and gunc (<a href="https://link.springer.com/article/10.1186/s13059-021-02393-0">Orakov et al. 2022</a>) results.</p> <h3>Multilocus sequence typing</h3> <p>Sequence type (ST) was determined using fastmlst (<a href="https://journals.sagepub.com/doi/10.1177/11779322211059238">Guerrero-Araya et al. 2021</a>) with the `ecoli#1` database.</p> <h3>PopPUNK&nbsp; clustering</h3> <p>Sequence clusters (SC) correspond to the database available from <a href="https://zenodo.org/records/12528310">https://zenodo.org/records/12528310</a> and were created using PopPUNK (<a href="https://genome.cshlp.org/content/29/2/304.short">Lees et al. 2019</a>).
